SIST EN 17860-2:2024/oprA1:2025

Overview

SIST EN 17860-2:2024/oprA1:2025 is a European standard developed by CEN under Technical Committee CEN/TC 333, focusing on the mechanical aspects of lightweight single track carrier cycles. This amendment revises specific scope definitions and test run requirements, reflecting the evolving market and use cases. The standard applies to single track carrier cycles, including those with electric assistance, with a maximum gross vehicle weight defined as:

• Up to 300 kg when intended for combined private and commercial use.
• Up to 250 kg when intended for private use only.

This standard is a key part of the EN 17860 series, dedicated to standardizing carrier cycles and ensuring safety, performance, and reliability in their mechanical construction.

Key Topics

• Scope Clarification: The amendment removes the distinction between "both private and commercial use" and "solely private use" in some clauses, streamlining requirements to better suit industry needs.
• Mechanical Requirements: Specific guidelines on materials, frame construction, durability, and load-bearing capacity tailored to lightweight single track carrier cycles.
• Test Procedures: Detailed descriptions of test runs verifying mechanical robustness and safety, with amendments refining test conditions.
• Compatibility with Electrical Assistance: While part 2 deals with mechanical aspects, electrical power assistance requirements are addressed in part 5 of the EN 17860 series.
• Weight Classification: Clear definitions of maximum gross vehicle weights ensure proper categorization and compliance.

Applications

SIST EN 17860-2:2024/oprA1:2025 targets manufacturers, designers, and safety authorities involved in the development and regulation of lightweight single track carrier cycles. These cycles are crucial for:

• Urban Cargo Transport: Optimizing goods delivery in congested city environments with lightweight, maneuverable carrier cycles.
• Commercial Use Vehicles: Providing reliable cycles suited for various commercial tasks, with robust mechanical standards ensuring safety.
• Private Use Cycles: Facilitating personal cargo transport with lightweight carrier cycles that meet defined mechanical safety requirements.
• Integration of Electric Assist: Allowing for up-to-date designs that incorporate electric assistance without compromising mechanical integrity, referencing complementary standards for electrical aspects.
• Regulatory Compliance: Helping manufacturers align their products with European safety and quality benchmarks, facilitating market access.

Related Standards

• EN 17860-1: General requirements and terminology for carrier cycles.
• EN 17860-5: Requirements specifically related to electrically power-assisted carrier cycles.
• ISO and CEN Bicycle Standards: Additional mechanical safety and performance standards that relate to load-bearing and structural aspects.
• National Standards: Adoption as a national standard in CEN member countries, such as SIST EN 17860-2:2024/oprA1 in Slovenia.

By adhering to SIST EN 17860-2:2024/oprA1:2025, stakeholders ensure that lightweight single track carrier cycles meet stringent mechanical criteria, enhancing safety and durability for both private and commercial applications while supporting the growing demand for sustainable urban transport solutions.
